you don't have to scream at me in the title man 😢

Given how many times Constantinople has been besieged I'm sure some joke is in the offing. Great video.
@
Feels like this video is less well researched than wikipedia, especially the maps
@
This siege also inspired the hymn to the Theotokos, Ti Ipermaho, or in English, To Thee the Champion Leader

Awesome vid!

The term Sassanid Empire is incorrect; the correct term is Eransahr, meaning the Empire of the İranians. Although the Sassanids were a dynasty of Persian origin, the empire was not solely a Persian state; it was a shared state of all Iranian peoples, and the Persians were the cultural heart of this empire. The Sassanid rulers called themselves not the Shah of Persians, but the rulers of the Iranians (Shahanshah of İranians).

Another excellent presentation but now there is a ad for further videos on the screen that cannot be dismissed.
Somewhat distracting!!

This was uploaded 2 minutes ago how do you already have a question about the video lol

Should have mentioned the battle at Lycus where Heraclius or his brother Theodore destroyed the other Sassanian army under Shahin while Shahrbaraz' force besieged Constantinople. Possibly the most important Byzantine victory of the entire war.

Ah, imagine the "what if", if these wars hadn't happen when they happened...

The distance from the Persian heartland was too far and they couldn't bring siege equipment. And they had no reliable means to transport it across the protected waters. Nor could they coordinate effectively with their allies. Only the Avars and Slavs were positioned for a proper siege from the western direction but they lacked resources, technology, and knowledge/skill in siegecraft, especially in comparison to the Sassanids. The walls and defences of Constantinople were also extremely strong. Though the Persians were literally across from Constantinople raiding and sacking the area of chalcedon at will on the other side of the bosporus. This was their furthest conquests since the days of the Achaemenids.

Small critique: your 3-D rendering of the Theodosian walls contains Yedikule Hisarı. This was not built until 1453 CE by the Ottomans. The area should only have Khryseia Pyle, the "golden gates" which were built 388-391 CE, and upgraded 425 CE.

What would’ve happened had Maurice had more popularity and not been deposed…

Those big beautiful walls are the main reason East Roman Empire survived for 1000 years. Serious unit of a wall.

Constantinople was besieged roughly 20-36 times throughout its history.

Constantinople surviving multiple sieges throughout the centuries is nothing short of amazing. It is truly a unique city with a grand history behind it.
